Plain semi auto bolt carrier groups, 4140 steel barrels, 1-9 twist rifling, commercial buffer tube. Poor finish, etc. Back in the early days of ar15s they might have been great but now we have people who make a much better gun for the same money.

The carbon 15 has a lot of problems. Google them. It's not a problem if you are looking for a range toy but for a serious use weapon it's a big thing to consider.Posted via Mobile Device

Ehh yeah for armory turn in sure. For basic maintenance? Heck no. If you ever need anything email me and I'll see what I can do. All you need to keep the m4 running is lube..it will run dirty just fine. Tooth brush, barrel rod, brush, chamber brush, eyelet. Everything else is optional.Posted via Mobile Device

These are notorious to sweat/bleed carbon, so I'm told. All I was issued was 2 cleaning rods and a eyelet. I ended up purchasing a otis kit, works great, even use it for my hunting rifle. I just couldn't bear to hear the grinding sound when you pull that charging handle back after being covered in sand.

Maybe you can answer another question for me. Sitting on a BZO range, the rifle would always misfeed on the 2nd round out of 3. Even did it on the Qual range to. Tap, rack, banged the 3rd round and functioned fine for the rest of the mag. Insert a fresh mag same thing, 2nd round misfeed, it was doing it all day. Usually no big deal, but only getting 34 out of 40, part of it being 3 misfeed's gets fustrating when your looking at your score for promotion points.

I just found this thread and wanted to add my 2 cents. First I Don't own a AR so I am going to stay out of any discussion as to which is the best manufacture. My assault rifle is the Israel Tavor chambered in 5.56. I am a fan of the Bull Pup design and own several in different calibers.

I will recommend to stay with NATO ammo because during the Ammo shortage It was the most available. However that doesn't mean there aren't other excellent rounds

I have several Suppressors from 22 on up to 308. The type of ammunition makes a big differences in whether the shot sounds like a whisper or a aloud boom box. In the case of Pistols, the Barrel length can play a important part. My PPK with a short barrel is much louder than my Rugger 22/45 with just 2 inches longer barrel. Fact is my 22/45 is almost as quite with supersonic ammo as it is with Subsonic. But My 10/22 is really quite with Subsonic and much louder with super sonic.

OK HERE IS THE POINT I WANT TO MAKE: 300 Blackout is a round that was developed especially for suppressors. If you want to shoot Medium large game quite, this is the Gun to buy. I don't own one but have shot my suppressed 5.56 next to the 300 Blackout suppressed round. The Difference is Huge and My 5.56 is fairly quite. The 300 Black has more Knock power than a 5.56 also.

Nato 7.62 X 51 Round compared to the Mosin Nagant/AK 7.62 X 54. The 7.62 X 54 round is the oldest round still in use by any Military. The Big Mess up is it is just a hair bigger than the 308/7.62 X 51 Nato round. Therefore the AK 7.62 X 54 can shoot the Nato 7.62 X 51 Round. But the 7.62 X 51 CAN"T shoot the 7.62 X 54 Round.

In 1964 & 65 we still had the M 14 and the newer at the Time M 16 were messing up. They were in constant need of Cleaning and then they still jammed or wouldn't eject shells. While AK are better at 200 yards and under they shot just as good with Nato Ammo as Nosin Nagant ammo.
